The Owl Comes Into Its Own

Natalie Angier in The New York Times:

Owls are a staple of children’s books and cultural kitsch — here wooing pussycats in pea-green boats and delivering mail to the Harry Potter crew, there raising a dubiously Wise eyebrow in the service of snack food. Yet for all this apparent familiarity, only lately have scientists begun to understand the birds in any detail, and to puzzle out the subtleties of behavior, biology and sensory prowess that set them apart from all other avian tribes.

Researchers have discovered, for example, that young barn owls can be impressively generous toward one another, regularly donating portions of their food to smaller, hungrier siblings — a display of altruism that is thought to be rare among nonhuman animals, and one that many a small human sibling might envy. The scientists also discovered that barn owls express their needs and desires to each other through a complex, rule-based series of calls, trills, barks and hoots, a language the researchers are now seeking to decipher. “They talk all night long and make a huge noise,” said Alexandre Roulin of the University of Lausanne, who recently reported on barn owl altruism in the journal Animal Behaviour with his colleague Charlene A. Ruppli, and Arnaud Da Silva of the University of Burgundy. “We would never put our nest boxes in front of a farmer’s bedroom, or the person wouldn’t be able to sleep.”
